4.7 rebuild & opinion

On the Dakota web board there is a guy running a homebuilt turbo on his 4.7 and it rips. It also has held up fine to the boost last time I checked but that has been a couple of years now. They are good motors with potential but were kind of forgotten by the factory when they started doing 5.7 Hemis. I think it actually is bigger, heavier, and costs more to manufacture then the 5.7. It didn't get much better gas mileage either. The factory was boosting this motor on a couple of concept cars they made. Makes me think it might be a better design for taking boost then 5.7 but like I said the factory seems to have lost interest in it. I think Allpar has a good write-up on it.
